Strings of holiday lights can be designed in one of two ways. In some strings of lights‚ each light is connected to the others along a single wire (in series). In others‚ each light is attached to its own wire (in parallel). Suppose a single light bulb burns out. How do you think

Light Reflection and Refraction Pre-Lab using PhET I) Introduction: When a light ray strikes a smooth interface separating two transparent materials (like air‚ glass‚ or water)‚ the wave is partly reflected and partly refracted (or transmitted) into the second material. For an example of this‚ imagine you are outside looking at a restaurant window. You can probably see both the inside of the restaurant (from the refracted light) and some of the street behind you (from the reflected light). Similarly

What is Magnetism? Properties of Magnets: Magnet: any material that attracts iron and materials that contain iron Magnets attract iron and materials that contain iron. magnets attract or repel other magnets. In addition‚ one part of a magnet will always point north when allowed to swing freely. Magnetic Poles: Magnetic Pole: any magnet with 2 ends‚ each is called a magnetic pole. Magnetic poles that are unlike attract each other and magnetic poles that are alike repel each other. Magnetic

Be sure to include in your explanation the terms positive and negative charge‚ electric field line and explain how mass affects the motion of the “puck.” This simulation project is all about getting the puck into the goal while surround the puck with using few positive and electric charges. The positive charges

speaking about magnetism and its use in our everyday lives‚ you can learn the SECRETthe secret of magnetism! A true scientist would be glad to share his secrets through experimentation. Thus‚ I will share the secret with you. It begins with sciencephysics‚ to be exact: matter and energy‚ conduction and induction‚ magnetizing and demagnetizing. All will be explained in my science project. More importantly‚ to discover through experimentation that the secret behind magnetism could be its power

discussion on magnetism to Thales of Miletus‚ who lived from about 625 BC to about 545 BC.[1] Around the same time‚ in ancient India‚ the Indian surgeon‚ Sushruta‚ was the first to make use of the magnet for surgical purposes.[2] There is some evidence that the first use of magnetic materials for its properties predates this‚ J. B. Carlson suggests that the Olmec might have used hematite as a magnet earlier than 1000BC[3] [4] In ancient China‚ the earliest literary reference to magnetism lies in a 4th-century

Electricity and Magnetism Electricity Circuit symbols Potential difference The energy which is delivered to an electric circuit comes from the supply. The greater the potential difference of the power supply the more energy is delivered. Potential difference is measured in volts‚ which has the unit symbol V. Cells in series The more chemical cells that are connected in series the greater the potential difference that they supply. The potential difference of a number of cells connected

Basics of Magnetism by Ron Kurtus (revised 29 January 2013) Magnetism is a force of attraction or replusion that acts at a distance. It is due to a magnetic field‚ which is caused by moving electrically charged particles. It is also inherent in magnetic objects such as a magnet. A magnet is an object that exhibits a strong magnetic field and will attract materials like iron to it. Magnets have two poles‚ called the north (N) and south (S) poles. Two magnets will be attacted by their opposite poles
